ful Improvements in Refrigerator ehicles. Fig. 1 and of which the following is a specification. Fig. a is a sectional View on'plane 4-4,

My invention relates to vehicles and par- Fig. 2. ticularly to an improved refrigerator truck Referring to the drawings, the truck 1 for distributing and delivering ice cream shown comprises the chassis frame 5 mount- 65 and the ingredients for cooling mixture such ed on the wheels 6, the engine E, drivers as ice and salt. seat and canopy 7 being at the front of the Among the important objects of my inchassis. The space behind the driversseat. vention are: to provide a vehicle body havtaken up by my improved mechanism' for ing a refrigerator section so constructed and storing cream and ice. The entire structure 70 arranged that a large number of ice cream is supported on cross beams 7 on'the chassis cans may be accommodated and conveniently frame 5 and the structurejhas two sections, located for handling to provide construction namely the cream storing section ""8 and the and arrangement whereby in a vehicle body ice storing section 9. The sections have a having refrigerator and also ice and salt common floor or bottom wall 10. The cream 75 storage sections. ice cream, whether in cans storage section body part comprises outer or in paper packages. or however packed, and inner walls 11 and 12 separated by space does not come in contact with the ice or salt. for receiving temperature insulating mateor the cooling mixture. nor do the ice cr-am rial 13 such as cork. Preferably also, the

receptacles, or containers, come in contact outer and inner walls are. lined on their 80 with the ice or salt, or the cooling mixture; inner faces by sheet material 14 such as tar to provide improved construction and arpaper which assists in temperature insularangement which will enable maintenance of tion and is especially useful in preventing the proper temperature of the cream with circulation of air. The cream section body little ice consumption; to provide construcpart is open at the top, the edge 15 of the 85 tion and arrangement which will eliminate opening flaring. To close the openingcover the necessity of frequent ice replenishment structures 16 and 17 are provided hinged at in the refrigerator to thereby effect. saving their sides. and fitting together at their inin labor, ice and salt; to provide construct-ion ner ends, suitable handles 18 being proand arrangement which will permit carrying vided by means of which tllGCOVQlS may be so of a large quantity 'of ice and salt to be readily manipulated. The covers at their furnished customers for use in their re edges are beveled to fit the flaring mouth of frigerators in which the cream to be sold thecreani storing body structure. by them is stored; to provide construction 'itliin the refrigerator body structure is and arrangement. whereby the ice and salt the sheet metal container frame 19 whose are readily accessible without requiring front is open and registers with the front climbing back and forth on the vehicle: to wall of the body structure. This container provide construction and arrangement of inframe at its other sides is spaced away from sulating walls which will eificiently insulate the body structure sides and also from the the refrigerator structure and the ice storcover structure so as to leave surrounding ice ing compartment so as to prevent ingress of space for receiving the cooling medium such heat and egress of cold; and in general to as ice and salt. As the body structure walls provideadelivery truck ofthe class described are of wood. the inner wall is preferably which will greatly facilitate the handling protected against the salt and moisture by so of cream with a great saving in time and a lining 20 of sheet metal. The container labor, and which will insure maintenance 19 is divided into an upper and a lower co1 n of the proper temperature of the cream with partment by the partition or shelf 21. In a minimum consumption of ice. the side wall of the refrigerator body struc- On the accompanying drawings, I show a ture are the openings 22, 23 and 24 for .55 delivery truck in which the various features which the door structures 25, 26 and 27 are ily accessible from the ground so that. cans can readily be removed from or inserted into the lower compartment by a man standing on the ground. In order to make the upper compartment readily accessible, a

step 28 is provided on which a man can stand when taking or returning cans in the upper compartment. The cover structure and the various doors are constructed in the same manner as the body structure. They each have inner and outer walls lined with suitable sheeting and filled in between with temperature insulating material.

I have found that by sub-dividing the ice containing space. great etliciency results, the ice lasting a. much longer time. 1 therefore provide vertical partitions 29 between the sides of the container 19 and the body structure to sub-divide the ice space into vertical pockets or compartments tit). These partitions terminate a sutlicient distance above the bottom of the ice space to permit free circulation of water to the drain pipes 31 which extend downwardly. When the covers 16 and 17 are sprung open ice can be readily charged into the compartments togetherwith the necessary quantity of salt and sufficient ice is charged into cover well the topof vthe container 19. 'lhecompartments prevent shifting and packing of the ice due to bumping and jolting of the vehicle during travel and the ice particles are thus held in more etiicient position for the generation of cold. I have found that with my improved sub-divided ice arrange ment and the surrounding temperature insulating walls that it is necessary to replenish ice only twice a week in comparison to replenishment morning and night necessary in prior constriu-tion.

The section 9 between the drivers seatand the refrigerator section is in the form of a rectangular tank for holding ice. and taking up part of this tank is a receptacle 32 for salt. a supply of ice and salt being usually provided the customer for use in the refrigerator in which he stores the cream bought. Like the refrigerator structure. the ice tank has outer and inner walls 33 and 34 lined by suitable material 35 and filled between with cork or other temperature insulating material 36. The tank has the ice inlet opening 37 provided with the door structure 39 suitably hinged. and constructed to snugly fit the opening. Like the walls'of the tank the door has double walls and is filled with temperature insulat ing material. At the side the tank has the outlet opening 39 from which ice can be removed into suitable pails by means of suitable instruments as for example, a shovel. sliding ,door 40 slida-ble in a frame -10 isprovided for controlling this opening. Instead of shoveling the ice. it can be caused to flow from a tank into the receptacle by opening the door to the desired degree.

The salt receptacle is entirely within the ice tank and on the same side with the ice discharge door. 40 the salt box has upper and lower openings 41 and 42, these openings being provided with sliding doors 43. and 44 respectively. The upper opening is used for charging in salt and the lower opening is used for discharging salt. It is evident that instead of having the various doors only at one side of the vehicle, a duplicate set of doors could be provided on the opposite side so that access could be had to the various compartments and ingredients from either side of the vehicle. The steps 28 and a similar steps 45 at the opposite side of the vehicle can run full length of the body so that ready access can be had to the various side doors and particularly the top covers. .it the rear end of the vehicle a frame 4-6 may be provided for. re-

ceiving empty cream cans.

I thus provide an improved delivery vehicle which greatly facilitates the. delivery of cream and ice. The arrangement is such that very little climbing is necessary as nearly all the work can be done from the ground. The improved construction of refrigerator section involving the sub-- divided ice space surrounded by temperaturevinsulating walls efiects considerable saving in labor and cooling material, it being necessary to replenish the ice supply only after several days. The ice tank has a large capacity and the ice is protected against melting and wastage by the temperature insulating walls. The salt is also protected against moisture and wastage is prevented. As the workman need not climb up on the vehicle. standing room for him can be eliminated and thus more space is available for storage purposes. ln old constructions considerable floor spaceis required for the workman who is required to climb on to the vehicle to get at the ice and the cream.

Having described my invention. I claim the following:

In a vehicle of the class described. the combination of the running gear. a rec tangular structure mounted thereon and divided into a refrigerator section and an ice and salt section. said structure having temperature insulating double walls. a container within the refrigerator section spaced away from the walls thereof. vertical partitions dividing said space into ice compartments. a side opening leading to said container. a door for said opening. an inlet ion terior of said structure, ice inlet and outlet 1 openings for the ice section, a salt'bin within the ice section, and openings leading to said salt bin from the exterior of said struc- J10 ture.

In witness whereof, I hereunto subscribe my name this 9th day of August, A. D
